Learn Your Pet's:
Heart Rate
Heart Rhythm
Respiratory Rate
Respiratory Effort
Mucous Membrane Color
Capillary Refill Time (CRT)
Rectal Temperature
Hydration
To determine your pet's:
Heart rate:
Listen to the heart with a stethescope, best heard on the left side of the body. When the left front leg is flexed close to the body and back slightly, the point of the elbow should lay against the chest and fall approximately over heart. In very large dogs with a deep chest, it may be difficult to hear the heart. To prevent panting in dogs, it may be necessary to close the mouth gently. Do this only if the dog is breathing comfortably.
Take the pulse:
1. Inside the hind leg, close to the body wall.
2. Front paw, between 3rd and 4th bones on top side of "hand"
Normal heart rates
Dogs: 70-120. Larger dogs have slower heart rates than smaller dogs.
Cats: 140-180. Stressed cats at a veterinary clinic often have a heart rate of ~ 200.
Heart rhythm:
In both cats and dogs, the sounds heard should be "lub-dub, lub-dub, lub-dub". A whoosh sound indicates a cardiac murmur, and may significant. "Extra" heart sounds or an irregular rhythm not associated with breathing (dogs only) should be noted. Normal, healthy dogs may have what is called a "respiratory sinus arrhythmia" - this means that the heart rate increases when the dogs inhales, and slows when the dog exhales. This does not signify a problem.
Respiratory Rate:
In both cats and dogs, a resting respiratory rate should be between 16-40 breaths per minute. Obviously, dogs sometimes pant. Cats, however, should never breathe with an open mouth.
Respiratory Effort:
A normal breath should be very smooth, and your pet's chest can be observed to gently rise and fall. Note if your pet is having difficulty inhaling, inhales in a "jerky" manner with several quick inhalations per each exhalation, or has notable abdominal movement associated with breathing.
Mucous Membrane Color:
Mucous membranes include the gums (most commonly used), the tissue of the inside of the eyelids, and the insides of the prepuce or vulva. Normal coloration is a healthy pink. Some dogs have naturally pigmented oral mucous membranes, and must be examined in one of the latter locations. Cats normally have paler membranes than dogs, so be sure to examine your cat when healthy to obtain a normal baseline.
Blue/purple membranes indicate a lack of oxygen being delivered to the tissues and constitute an emergency.
Brick red membranes may indicate shock.
Pale pink or white mucous membranes indicate severe anemia or sudden blood loss.
Capillary Refill Time (CRT):
When pressure is applied to a mucous membrane to blanche the color from it, the time it takes for the color to return should be 2 seconds or less. A longer CRT indicates that the heart is not able to return blood to those tissues appropriately.
Rectal Temperature:
Normal temperature for both dog and cats: 100°-102.5° F.
Digital thermometers work well, but discuss with your veterinarian insertion recommendations.
A dog that has just returned from a walk on a hot day will have a higher temperature, up to 103.
A temperature lower than 98° F in a cat often proceeds multiple organ failure and death.
Hydration:
Feel your pets' gums. If the gums feel tacky and dry rather than moist, dehydration is estimated at 3-5% minimum.
A less sensitive way of determining the hydration status of your pet is the skin tenting test. When the skin is pulled up into a "tent" it should return quickly into place.
One additional method of assessing hydration is more subjective, and involves observing the eyes for a dull or sunken appearance.
